Psychiatry was invented by a man named Freud and was based on his theory that people had no way of knowing why they were unhappy or behaved peculiarly, because the origins of the problem were hidden from them, lurking in what he called the subconscious, and only a trained, expensive specialist could uncover and uproot them over the course of a long, expensive treatment.

I suppose none of us doubts that there is such a thing as the power of suggestion and that it can produce very great results indeed, and that it is _par excellence_ a hidden power; it works behind the scenes, it works through what we know as the subconscious mind, and consequently its activity is not immediately recognisable, or the source from which it comes.

Garden of the Mind which has levels from the conscious mind, or pea, to relaxed awareness and creativity, the carrot, to the onion, which she called the subconscious, where we find memory and what's repressed.
